解答ステップ

Represent the numbers with

x

First number : x

Consecutive number 1 : x + 2

Consecutive number 2 : x + 4

Consecutive number 3 : x + 6

A.T.Q.:

x + x + 2 + x + 4 + x + 6 = 20

解く

x + x + 2 + x + 4 + x + 6 = 20 : x = 2

x + 2 = 2 + 2 = 4

x + 4 = 2 + 4 = 6

x + 6 = 2 + 6 = 8

The numbers : 2, 4, 6, 8
